1973 Oakland Athletics World Championship Team Signed Baseball, PSA/DNA 8.5. A repeat performance as World Champions this season cemented this rowdy band's legacy as one of the greatest clubs in the history of professional baseball, and has served to elevate team balls to "must have" status among serious collectors. This fine OAL (Cronin) example boasts an impressive roster of twenty-nine signatures from Charles O. Finley's celebrated crew, including the trio of twenty-game winners Blue, Hunter and Holtzman, as well as Hall of Famer Fingers. The Reggie Jackson example is clubhouse. Other notables include Blue Moon Odom, Rudi and manager Dick Williams. Condition is stunning, ranking this among the very finest available in the hobby. Not a signature dips below 9/10, and the ball is ivory white. Full Grading LOA from PSA/DNA, NM-MT+ 8.5. Auction LOA from James Spence Authentication.
